Diagnosis Procedure with Warning Lamp Function (Without CONSULT-II)NES000K6
DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel when the tire pressure becomes low. The control unit (low tire pressure warning control
unit) of this system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the tire pressure monitoring system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing. Regarding location of tire pressure warning check connector, refer to PG-62, "
HARNESS" .
Test item Content
BUZZER This test is able to check to make sure that the buzzer sounds.
WARNING LAMP This test is able to check to make sure that the warning lamp turns on.
